Dear friends,
These days ,I am learning something related to linear list.In implmenting the function of realloc.I have been pullzed for several days,although I can use "include" method to directly use the function.
However , I　deeply wonder that how can I write my own code to solve such questions in c++.
Willing to receive yours help.
Thanks a lot.
